STRIKE-PLATE FOR LOCKS.

Specification of Letters Patent.

Application filed August 15, 1913.

Patented Apr. 21, v1914.

Serial No. 785,005.

To all whom t may concern Be it known that I, JOHN H. AMES, a citizen ofthe United States, residing at Eddington, in the county of Penobscot andState of Maine, have invented new and useful Improvements in Strike-Plates for Locks7 of which the following is a specification. A

An object of the invention is to provide a strike plate for use inconnection with doors and the casings thereof and the locks on doors forlocking the doors relatively to the casing.

The invention embodies, among other features, the provision of a strikeplate having adjustable means whereby the bolt and latch of a lock canbe properly received in the strike plate when it is desired to securethe door relatively to the casing thereof.

The invention further embodies the provision of a simple and durabledevice which is arranged in the casing of a door and which includesadjustable means whereby, when the latch and bolt of a door lock areengaged with the strike plate any rattling` of the door relatively toits casing will be prevented.

In the further disclosure of the invention reference is to be had to theaccompanying drawings, constituting a part of this specification, inwhich similar characters of reference denote corresponding parts in allthe views, and in which:

Figure 1 is a front elevation of the strike plate; Fig. 2 is a sideelevation; Fig. 3 is a vertical transverse sectional view taken on theline 3 8 in Fig. 1, showing the strike plate applied to a door casing;Fig. 4 is a vertical sectional view taken on the line 4-4 in Fig. 2;Fig. 5 is a horizontal sectional view taken on the line 5-5 in Fig. 2;and Fig. 6 is a horizontal sectional view taken on the line 6 6 in Fig.2.

Referring more particularly to the views, I disclose a box 10 carried bya member 11 having its ends 12 projecting beyond the ends of the box,with the said box adapted to be received in a recess 13 in a door casing14 so that the ends 12 can have suitable screws 15 passed therethroughand extend into the casing 14 to secure the box 10 in rigid positionthereon, a lateral extension 16 being formed with the member 11 andprojecting from one side thereof as shown, the said member being adaptedto lie against the edge of the door casing and constitute the usualstrike for guiding the bolt of a door into engagement with the strikeplate, as will be hereinafter more fully disclosed.

The member 11 carrying the box 10 has an opening 17 which constitutesthe opening for the box 10 and the said member 11 is grooved to providea longitudinal track 18 on which is mounted to slide a plate 19 providedwith a latch opening 2O and a bolt opening 21, through which the latchand bolt of the door are adapted to extend, as will be readilyunderstood. The plate 19 inchicles a cross piece 22 which forms theopenings 20 and 21 and the said cross piece is preferably provided witha slot 23 through which passes a screw 24 adapted to extend into therear wall of the box 10 in order to secure the plate 19 in an adjustedposition on the box. Now it will be readily apparent that by looseningthe screw 24 the plate 19 can be adjusted vertically on the member 11 ofthe box in order that the latch and bolt can easily pass through theopenings 20 and 21, it being thus seen that a means is provided wherebythe latch and bolt will readily spring into the box when the door isclosed relatively to its casing and upon which the member 11 carryingthe box 10 is mounted.

A plurality of adjusting screws 25 pass loosely through a side wall 26of the box 10 and loosely supported on the screws 25 are a series ofbars 27, the said bars being provided with slots 28 in which are adaptedto repose nuts 29 having threaded connection with the screws 25, thesaid nuts 29 being held against rotation by the configuration of theslots in which they repose. Now it will be readily apparent that afterthe plate 19 has been adjusted in order that the latch and bolt of thelock will readily pass through the openings 20 and 21 when the door isclosed relatively to its casing, an adjustment of the bars 27 can beobtained by operating the screws 25 so that the bars will be advanced orretreated with respect to the side wall through which the screws pass,thus providing a means whereby the bars, when properly adjusted, will beengaged by the latch and bolt of the door lock when the same passthrough the openings 20 and 2l so that the latch and bolt bearingagainst the bars 27 will prevent the door from rattling relatively toits casing, it being understood that the distance between the faces ofthe bars 27 and the opposite wall of the box can be increased ordecreased by adjusting the b ars proportionately to the thickness orwidth of the latch or bolt so that the strike plate described herein canbe employed to receive the latch and bolts of door locks in which thelatch is of a diierent size from the above, one of the bars 27 beingadapted to be engaged by the latch of the door lock and the other bar bythe bolt of the door lock. The plate 19 slidable on the track 18 isadapted to lie flush with the edge of the door casing as shown, and canbe readily adjusted vertically on the member l1 as mentioned heretofore,it being further apparent that when the plate is in position the screws15, holding the member 11 in rigid engagement with the door casing, willbe invisible to the eye of the observer, thus preventing children fromtampering with the screws and loosening or removing the member l1 fromthe door casing.

Having thus described my invention, I claim:

1. In a strike plate for locks, the combination with a box adapted tolie within a door casing, of a member supporting the box and having itsends projecting beyond the ends of the box and adapted to receive screwstherethrough to secure the box and member to the door casing, the saidmember having an opening therein, a track formed on the member, a plateprovided with a plurality of openings and mounted to slidelongitudinally on the track to normally cover the screws securing themember to the door casing, and means engaging the box for securing thesaid plate in an adjusted position on the said member.

2. In a strike plate for locks, the combination with a member for rigidattachment to a doo-r casing, of a box carried by the member and lyingwithin the door casing, a plurality of screws passing through projectingends of the said member to secure the member and box rigidly to the doorcasing, a plate mounted to slide on the said member and normallycovering the said screws, and a screw passing through a slot in the saidplate and having connection with the said box for securing the plate inan adjusted position on the said member.
